Question

What week is the earliest potential survival expected if the baby is pre-term ? List two important developments from the 2nd trimester and the 3 trimester.

Answer 1

Ans-

The earliest potential survival expected week if the baby is pre term is 28 weeks. This is because baby born before that will have high risk for successful survival. The baby which is born on 28 week could potentially survive because lungs are formed uptill then but during a preterm, the efficiency of lungs is not completely well developed so they need special aids for breathing.

Ans-

The two important developments from the 2 nd and 3 rd trimester are-

First the heart that is developed during first trimester , the sound of heartbeat can be detected during second trimester. The baby grows in size and weight and a layer of skin develops on baby which is called vernix . The formation of middle ear is completed in second trimester and major organs like liver and pancreas are also formed . In the beginning of third trimester, all the organs are developed in the baby and the it starts showing movement inside the womb.Lung formation is not fully done till this time. During 28 th week, full development of lungs also take place.This could result in lesser movement of baby towards the end.So these are the major events.
